When I logged onto Fitday, my calorie intake requirement had changed.... A LOT! Instead of 2,330 calories needed (without exercise), now it says 1,075.... what's going on? I didn't change anything.. anyone else experiencing this??

Yes! although mine was not as drastic, it went from 2100 roughly to 1900 I dont know what going on though

mine had change, only b/c I had changed it. You can probably go back and manually change it. LMK if you don't know how to do so.

As you lose weight, you'll notice you get to eat less - I know - not fair! The numbers you cited didn't look right - make sure your height and weight are correct. If you made yourself 54 inches instead of 5'4" (for example), or missed a number in your weight it'll throw the numbers off.
